The Reveille quest starts automatically after Brotherhood of Steel's main forces arrive in Commonwealth. It happens more or less after you walk out from Fort Hagen during the Reunions main quest. Important! The mission will not activate if you have previously joined the Brotherhood of Steel by talking to Paladin Danse on the Cambridge Police Station and completed few quests for him.
The quest is very simple to complete. First you must go close to Boston Airport where the ship is docking. Talk to any Brotherhood's knight and the quest will end. You can also go directly to Cambridge Police Station. Once you get there, the quest will end.
Quest rewards: experience points.
